FPGA implementation of stereo matching algorithm for depth estimation.

Abstract

Computer vision is an artificial intelligence branch developed for machines to perceive image and videos. It interprets visual data (pictures or videos) to extract information. One of its fundamental concepts is defined as stereo vision; used to estimate 3-D information of the scene. During depth estimation, a process denoted stereo matching is considered as the complex part; it requires a considerable amount of time to execute on a processor which prevents the systemto reach its minimum speed (30 frames per second). The proposed solution is moving the complex part of the system to hardware, since the latter is faster than software. To implement stereo matching, different
